Hi there,

I am trying to find the integration formulas of Newton cotes over a tetrahedral cell. Any information is appreciated.

Look in Handbook of Mathematical Functions, Abramowitz & Stegun, eds. around Section 25.4.70.

That reference has been republished by Dover and is a great bargain addition to your reference library.

If that formula does not provide you with what you need, then there are other books on numerical quadrature that might be useful. IIRC, Stroud is the author of one such reference.

HTH.
